SPECIFICATION forming part of Letters Patent No. 402,281, dated April30, 1889.

Application filed June 11, 1888l Serial o. 276,721. (No model.)

.To all whom, t may concern:

Be it known that LALBEET W. SMITH, a citizen of the United States, and aresident of Haverhill, in the county of Essex and State ofMassachusetts, have invented new and useful Improvements inDial-Painting Machines, of which the following, taken in connection withthe accompanying drawings, is a specifia cation.

This invention relates to improvements in dial-painting machines, forthe purpose of spacing and numbering or otherwise marking watch-dials,and it is carried out as follows, reference being had to4 the`accompanying drawings, *wherein- Figure 1 represents a plan view of themachine. Fig. 2 represents a cross-section on the line A B, shown inFig. 1. Fig. 3 represents a cross-section on the broken line C D in Fig.l. Figs. 4, 5, and 6 represent, respectively, a front view, verticalsection, and bottom view of one of the vertically1novable stencils forspacing .and marking' the minute and hour divisions onv the dial. Figs.7, S, and 9 represent, respectively, a side View, vertical section, andbottom Vview of one of the vertically-movable stencils for marking thenumerals on the dial.

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings.

d in Figs. 1, 2, and 3 represents the baseplate of the machine, havingon its under side a circular peg or projection, c', adapted to beinserted in a perforation in the table-top b, on which the base c, ismade to rest during the process of paintingthe dials, and by having thebase a pivoted in this manner to the tabletop b the entire'machine maybe turned more or less around the axis of the said peg or pro j ection dto suit the requirements of the operator, so as to place the machinefrom time to time in the most favorable position convenient for theoperator to do the work.

c is a hand wristuest having a downwardlyprojecting circular-pin, c',that is journaled in a bearing, c ,that forms a part of a horizontalbar, c3, that is adjustable in and out in a horizontal direction in arecess made in the base-plate c, as shown in dotted lines in Fig. l andfull lines in Fig. 3, and by this arrangement said hand or wrist restmay be adjusted `out and in, as well as swung to any desired position,to suit the requirements'of the operator. After being adjusted, if sodesired, the said hand or wrist rest may be secured in place bysetscrews or equivalent devices, such being,'however, not shown in thedrawings.

On the top of the base-plate c are located two equal gear-wheels, cl ande., the teethv of which mesh into each other, as shown in Figs. 1, 2,and 3, said gears having the respective downwardly-projecting spindlesd. e', journaled in circular perforations in the base plate a, as shownin Figs. 2 and 3, so thatwhen turning one of said gears around its axisa corresponding movement will be imparted to the other gear.

. The gear eis the dial-support, on the top of which is temporarilysecured the dial F while in the act of being painted, said gear e havingin its upper side a series of annular grooves, c e, adapted to receivelthe downwardly projecting pegs on the und er side of the usualwatch-dials. The dial F is held from turning aroundl on the gear e bymeans of two pins, a central one, ci, that passes through the usualcentral dial-hole into a central cylindrical recess in the said gear e,and the pin c4, the lower portion ot which is equal in size to the lowerend of the central pin, c3, and having its upper end reduced, so as tofit and proj ect' through the second-hand hole inthe dial, as

shown in Figs. l, 2, and 3, and by this arrangement the dial, when thusplaced in ,position on the gear c, will partake of the rotaryniotion ofthe latter.

The gear d serves as a base and support for the marking or indexingdevice, and has for this purpose secured or attached to it the cir-`cular disk D', having twelve radial grooves, D in which are adjustablysecured the radial bars G G, adapted to slide out and in in said radialgrooves and to be secured in po sition therein by means ofspring-pressed pins d d, adaptedv to. be locked in recesses g g on thebars G, as shown in Fig. 2.

The radial bars G have in their outer ends vertical sleeve-bearings G',in which are vertically adjustable the spindles H, that are normallyheld in their highest positions (shown in Fig. 2) by the iniuence ofsprings 7g 71., su r roo rounding said spindles II, between the heads orbuttons 7L in their upper ends and the top of the bars G, or in anyother equivalent manner.

The spindles H are held from turning around in their respectivesleeve-bearings, as is usual in spindle devices of this kind. To thelower end of each spindle H is secured or made in one piece with it thetemplet or stencil I, composed of one or more feet ordownward'projections, 1li', with narrow intervening spaces z" 'i'between their lower ends, and a surrounding edge, i, with an interveningspace or opening, t, between its lower edge and that of the lower edgesof the feet or projections i' fi, as shown in Figs. 4, 5, 6, 7, 8, and9. These telnplets or stencils are made in shapes according to thespacing, numbering, or lettering that is to be made on the dials. Thestencil represented in Figs. 4, 5, and G is intended for use in paintingthe circles and radial divisions for the hours and minutes on the mainportion of the dial, and corresponding ones of smaller size are to beused for the same purpose on the second-hand part of the dial.

The templet or stencil represented in Figs. 7, 8, and 9 is for one ofthe numerals on the main portion of the dial, there being in all twelveof this kind, each shaped corresponding to one of the twelve numerals onsuch main portion of the dial. Smaller ones in a like manner are to beused in painting the reduced Iigures on the second-hand part of thedial. Other templets or stencils ymay be used in a like manner formarking the name or make of the watch, such being made substantiallylike those above mentioned, only diiering in form and shape according tothe figure or design that is to be produced.

For the purpose of retaining the wheels d e in rigid positions while oneof the stencils is pushed against the dial F, I employ a yielding orspring-pressed lever, E, the inner end of which is secured in a suitablemanner to the base-plate a, which lever has on its upper side a lockingprojection, E, adapted to project into any one of the twelve recesses c5on the under side of the gear-wheel e, as shown in Figs. 1 and 3.

In using the invention I prefer to use a number of the improvedmachines, all alike, except that the shapes of the stencils varyaccording to the marks, figures, or designs that are to be transferredin each to the dial. Thus, for instance, I may use one machine formarking the minute and hour divisions, another for marking the divisionson the seeond-hand. portion of the dial, another for marking thenumerals from one to twelve on the main portion of the dial, another formarking the numerals on the second-hand part of the dial, and anotherfor marking the makers name on the main portion of the dial, or in anyother suitable or equivalent manner, although all these different kindsof marks or designs maybe produced in a single machine simply bychanging the stencils or templets In using the machine, if the mainportion of the dial is to be painted, I secure it in place on the geare, as shown in the drawings-that is, concentric on top of said gear-theprojections on the under side of the dial being inserted in any of theannular grooves e on the gear c, as described, and the dial preventedfrom moving on said gear by means of the pins e3 and e4, passing throughthe respective central and second-hand holes of the said dial. Duringthis operation the geare is secured in place by means of the projectionE on the spring-lever E resting in one of the recesses c5 on the underside of the gear e, and as the latter is positively geared to the gear dthe latter and its stencil-carrier and stencils are also firmly held inaccurate positions relative to the gear c and its dial F. The stencil ortemplet opposite to the center of the dial is then depressed by theoperator pressing' on the button h until the under side of the templetrests against the top of the dial, when the operator paints, with abrush and suitable mastic enamel or color, on the dial in and throughthe openings fi 1&3 in the templet, after which the latter isautomatically raised to the position shown in Fig. 2 by the influence ofits spring h as soon as the operator relieves the pressure on the buttonh. The leverE is then depressed, causing the gear e to be liberated, andit and the gear d are then turned around, each one-twelfth of arevolution, until the nextrecess e5 on the under side of the gear e isautomatically locked to the projection E on the spring-lever E, when theoperation is repeated on a new place on the dial, and so on until theentire circumference of the dial is painted. In painting the second-handthe dial is secured to the gear in such a position that the hole for thesecond-hand coincides With that of the center of the gear e, thepositions of the pins e3 e4 being reversed, the radial stencil-carryingbars G G being correspondingly moved outward in their grooves D andsecured in such positions by means of the spring-pressed projections dand the notches g on the under side of said bars G, when a similaroperation takes place, and so on.

That I wish to secure by Letters Patent and claim is l. In adial-painting machine, the int-erineshing gears d e, journaled to thebase-plate a, the gear d having a series of verticallymovable templetsor stencils adapted to be moved to and from the dial secured to the geare, substantially as and for the purpose set forth.

2. In a dial-painting machine, the baseplate a. and the dial-supportinggear e, journaled to it and having means for securing to it the dial tobe painted, combined with the gear d, intermeshing with the gear e, aseries IOO IIO

of radially-adjustable bars, G G, mounted on the disk D von the gearI d,and a series of vertically-movable templets or stencils arranged onspindles in said bars Gand adapted to be moved to and from the dialVthat is being painted, substantially as and for the purpose set forth.

3. In a dial-painting machine, the baseplate a, having trunnion or pivota', adapted to be inserted in a corresponding recess in the support b,combined with the dial-supporting gear e and the intermeshing gear d, journaled to the said base-plate, and the radially-adjustable andvertically-movable stencils or templets I, all arranged and combinedsubstantially as and for the purpose set forth.

4. In a dial-painting machine, the dialsup Y porting gear e, having aseries of annular grooves, e, on its upper side, adapted to receive theprojections on the under side of the dial, and havingrecesses on yitsupper side for receiving the pins e3 e4, for holding kthe dial in placeonsuch gear, combined With the locking-lever E, having projection E',adapted to be locked into one of thev recesses e5 on the gear c,substantially as and for the purpose set forth. p

5. In a dial-painting machine, an intermittently-rotating dial-carryingdevice and an intermittently rotating stencilcarrying device havingradially-adjustable and vertically movable stencils or templets I,combined With an oscillating and horizontallyadjustable Wrist-rest,substantially as and for the purpose set forth. 3 5

6. In a dial-painting machine, an intermittently-rotatingtemplet-carrier and an intermittently-rotating dial-support and alocking and releasing device for securing said parts firmly in positionduring the operation 4o of painting the figures, marks, or designs onthe dial, substantially as set forth and described.

7. In a dial-painting machine, the templetcarrying gear c, journaled tothe plate a and V45 having a radially-grooved disk, D, a series ofradially-adj ustable bars, G, mounted in said grooved disk D', a lockingdevice, as described, for securing said bars in position, and thespring-pressed spindles Il, movable in 5o bearings on said bars G andprovided With stencils or templets I, substantially as and for theVpurpose set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two sub- 55 scribing Witnesses, on this 2d day of June, A.D. 1888.
